RADIATOR PROTECTOR.

Application led October 1, 1921. Serial No. 504,634.

To all whom t may concern.'

Be it known that I, RICHARD C. STEWART, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Radiator Protectors, of which the following is a speci -ficatiOI1.

from the radiator but against loosening under vibration incident to the vehicle travel or engine operation. Other objects will appear in the course of the ensuing description.

Fig. 16 is a partial front elevation of a. protector similar to that of Figs. 9 to 12, inclusive, showin a 'modified design of the apertures and rlbs. 1

As shown in Figs. 1 to 4, inclusive, a single sheet of material, such as sheet steel, is

formed with a continuous flange 1 pressed back from. its opposite upright edges and top edges, 1n the shape of the radiator shell Aof the vehicle; a forwardly distended bead 2 being formed throughout the length of the junction of this iiange 1 with the main part of the sheet, similar to the bead found on the front edge of such a shell. Also, the lower ends of this pressed-back flange 1, at opposite sides, are bent out horizontally, forming feet or lugs 3, and these have openings 4 through whichbolts 5 are passed to bolt the protector to the brackets 6 (Fig. 2) found on the radiator-including structure 7, in the way that the shell was bolted there- At `the middle of the top of this flange radiator shell thus displaced by the protector.

The upright and top extreme edge parts of the sheet, here the rear edge parts of the flange 1,' are formed to receive snugly the front edge parts of the radiator and engine hood of the vehicle; these edge parts being inset, leaving a continuous shoulder 10 throughout -the flange 1 (Figs. 2, 3 and 4) similar to that found along the rear edge of the usual radiator shell thus displaced. The lower part of this protector has rounded corners 11 and a straight lower edge, preferably provided with a slightforwardly bent flange 12,to strengthen it; this lower part thus being adapted to fit snugly within t-he bead 13 extending around the lower part of the radiator front as -found on the mentioned vehicles, as for instance, the Ford automobile'.

The main part of the sheet has a series of upright ribs 14 distended forward, extending about from the lower to the upper tank o-f the radiator, as from the tank 15 to the tank 15 infF ig. 2. These ribs 14, at their upper and lower ends, merge into the flat body of the sheet, being gradually less distended from a point some distance from the end, to the end. In this example, thse ribs are of V-shaped cross-section, preferably somewhat deeper than wide; and the sides ofthe V diverge in curve 16 with the intervening flat end part 17, forming the gradually less diS- tended rib end part, as clearly seen in Fig.

7. These sides of the V may continue paral-v l'el as at 18 in Fig. 8, with the intervening flat end vpart 19 accordingly shaped, to form the gradually less distended rib end part. The sheet is cut away between each two acljacent ribs 14, forming apertures 20; the spacing of the ribs 14 being considerab-ly greater than the rib width, and the apertures being the full width of the spacing. However, I prefer that the apertures be round-. cornered or otherwise provided with ample v extra metal in the corners, as by the fillets vof the edges.

21, strengthening the junctions of the ribs 14 with the main parts vof the sheet. The cross-section of the ribs may vary in different or the same guards, as for instance the rectangular-channeled cross-section of the rib 14 of Fig. 5, or one with diagonal corner p-arts, making a five-sided cross-section, as the rim 14" of Fig. 6.

In Figs. 9 to 12, the single sheet is dished forward to a less extent than in the previous example, having only the comparatively slight rearwardly projected flange 22, which preferably isontinued entirely around all Y This sheet is of a. size and shape that will result in this flange 22 fitting snugly within the before mentioned lower bead 13 of the radiator and within the bead 2 of the radiator shell 23 found ou the radiator. Coextensive with this shell 23. al further flange 24 extends laterally and upwardly f'nrom the flange 22, to fit snugly under the radiator-shell bead 2. lu some radiators, the lower bead A and panel P thereabove are absent; in which case my protector would have additional height to fit under the upper bead Cy (Fig. '9). The ribs and apertures in this example are the same as those of the previous example. To install this protector, the radiator shell 23 is unbolted' from its brackets 6 and slid up off' of the radiator structure: then the protector is placed against the front of the radiator, and

the `shell 23 is slid down ontothe radiator and aga-in bolted. The shell 23 thus holds the protector rigidly in place. by its bead 2 in front of the protector flange 24, and with the protector engaging downwardly, at its lower edge along the flange 22, with the bottom bead 13 of the radiator, where the flange 24 is absent'. rlhe rearwardly projected flange 22 stifl'ens the edge parts of the protector, thus. 'addin to this rigidity.

rlhe protector o Figs. 13 and 14 is similarl to that just described, but as shown, is provided with a rearwardly extended flange 25 joining the main part in a bead 26, entirely around the protector. This flange 25 and bead 26 strengthen the edges ofrthe protector so that it can function properly when supported merely at widely separated locations. as by the'lugs 27 formed on the radiator frame 28, over which lugs the upper and lower parts of the flange 25 fit, with bolts 29 through the flange and the respective lugs. Such a radiator structure is more common on motor-t-rucks and other large heavy motor vehicles; the frame of the radiator usually being al casting without any enclosure such as the shell of the passenger vehicle radiator. rlhe flanges .or lugs 27 are not found on such castings as usually made; so that this mounting requires that the radiators bemade with these. lugs with the attachment of such a protector contemplated. For vehicles of this character already provided with radiators of this kind, the protector of Figs. 13 and 14'can be attached as seen in Fig. 15,- where bolts 30 and 31 at the bottom and top, respectively, pass through the margin of the main part next to the side parts of the flange 25 at the bottom into the frame 32 of the vehicle, and at the top into a brace 33 which will be understood to extend back and down and be attached to the frame 32 as is known in the art. lln this case, as in the other example, the flange 25 affords the necessary stiffness to the edges of the protector, and the beadv26 adds to this stiffness.

Any of the protectors may have the design of its ribs and apertures varied as may be desired, for appearance. An example of such variation is seen vin Fig. 16, where the ribs 14 curve across each other, with alternate ribs meeting at a. single junction with the sheet main part, leaving various apertures 20', 20 and 20a. 'lhe rib junctions arc similar to those before described, preferably with the ample fillets 21', widening and strengthening these junctions with the marginal parts of the sheet.

Other variations in ornamental and structural design of the. protector may occur, depending upon conditions and upon the design of radiator structures to he equipped. Details of various examples may be interchanged; for' instance the protector of Figs.

1 to 4 may have a rearwardly inclined .flange intermediate of its main .part and its bead 2, similar to the flange 22 of Figs. 9 to 12, inclusive; or this flange 22 may be omitted in the latter example, so that the apertured and ribbed main part of the protector stands back nearer to the radiator. Therefore, while certain details are deemed preferable in connection with my invention, and I have shown and .described these rather specifically in elucidating the` construction and yuse of my invention, as is required, I do not wish to be Vunderstood as being limited to such precise showing and description, but having thus fully described my invention,
